As shown in FIG. 4, the controller 180 may arrange or provide anapplication (or applications) on at least one page included in a homescreen (S101). When the application is arranged on a specific page inthe home screen, the controller 180 may execute the application whenmoving to the corresponding page. Further, the controller 180 maydisplay an execution image of the application on the home screen of themobile terminal 100. For this, the controller 180 may map the page inthe home screen on which the application is arranged with theapplication and store the mapped result in the memory 160. That is,information on what application is arranged in the corresponding page isstored in the memory 160.

FIGS. 4 and 5 illustrate arranging applications on a home screen. Otherexamples may also be provided.

As shown in FIG. 5, the controller 180 may display a list L1 of itemsaddable to the home screen on the display 151 based on a control inputreceived from the user input unit 130 or the touch screen (of thedisplay 151) (S201). The items addable on the home screen may includeshortcut icons, widgets, folders, wallpapers, and/or home applications.The folder may refer to a group icon and the home application may referto an application installed in the home screen. When a home application4 a is selected from the list L1, the controller 180 may display a listL2 of addable home applications on the touch screen (of the display 151)(S202). When an application 4 b is selected from the home applicationlist L2, the controller 180 may arrange or provide the selectedapplication 4 b on the home screen (S203). According to an embodiment,the controller 180 may display the home application 4 b requested to bearranged or provided on a page of the home screen displayed on thecurrent screen. For example, when page 4 of the home screen displayed onthe current touch screen (of the display 151) is a fourth page and thehome application selected from the home application list L2 is a memoapplication, the controller 180 may install the memo application in thefourth page of the home screen. Further, the controller 180 may arrangeor provide the home application 4 b on a page other than the pagedisplayed on a current screen. The controller 180 may add a new page tothe home screen and may arrange or provide the selected home applicationon the newly added page. For example, when the home screen includesseven pages and a request is received to provide the memo application onthe home screen, the controller 180 may add an eighth page to the homescreen and may provide the memo application on the eighth page.

An execution image 4 c of the home application provided on the homescreen may be displayed on an entire area or a partial area of the pageon which the corresponding application is arranged. When the executionimage 4 c is displayed on a partial area of the page, the controller 180may downsize the execution image of the home application. Further, theexecution image may be displayed as a background image of the page onwhich the application is arranged. For example, when the memoapplication is arranged on the fourth page of the home screen, thecontroller 180 may display the execution image 4 c of the memoapplication on the entire area of the fourth page of the home screen.

As shown in FIG. 6, the controller 180 may enter into a mode forchanging a display size of an item 5 a (hereafter referred to as adisplay size changing mode) provided on the home screen based on user'scontrol input through the touch screen or the user input unit 130(S301). For example, when the item 5 a displayed on the screen istouched for a predetermined time, the controller 180 may enter into themode for changing the display size of the item 5 a. The controller 180may enter into the mode for changing the display size of the item 5 awhen the item 5 a is multi-touched. After entering into the display sizechanging mode, the controller 180 may change the size of the item 5 abased on a received drag input. As the size of the item 5 a is changed,the item 5 a may change in shape into a shortcut icon, a widget and/or ahome application. When the display size of the item 5 a increases bymore than a predetermined size, the controller 180 may transform theitem 5 a to a home application 5 b and provide the home application 5 bon the home screen (S302). The executing home application 5 b on thehome screen may be displayed on an entire area or on a partial area ofthe page on which the corresponding application is arranged. Theexecuting home application may be displayed as a background image of thepage on which the corresponding application is arranged.

Returning to FIG. 4, when an entrance into the home screen is requestedwhile the application is in execution (S102), the controller 180 maypause or terminate the executing application and enter into the homescreen (S103). The controller 180 may display any one page constitutingthe home screen on the screen of the mobile terminal 100 through thedisplay 151.

Referring to FIG. 17, when a shortcut icon 16 a displayed on the screenis touched for more than a predetermined time, the controller 180 mayenter into a display characteristic changing mode for the shortcut icon16 a (S1301). Upon receiving a drag input starting at an area where theshortcut icon 16 a is displayed, the controller 180 may change adisplayed size of the shortcut icon 16 a based on the received draginput. When the displayed size becomes more than a predetermined size,the controller 180 may transform (or change) the shortcut icon 16 a to awidget 16 b and display the widget 16 b (S1302). When the displayedshape is changed from the shortcut icon 16 a to the widget 16 b, thecontroller 180 may include an execution result of a correspondingapplication. Even though the displayed shape is transformed to thewidget 16 b, the controller 180 may continuously change the displayedsize of the widget 16 b based on a received drag input (S1303). When thedisplayed size of the widget 16 b increases, information displayed onthe widget 16 b may also increase. When the displayed size of the widget16 b is increased more than a predetermined size while being varied, thecontroller 180 may transform the widget 16 b to a home application 16 cand display the home application 16 c (S1304). When the widget 16 b istransformed to the home application 16 c, the controller 180 may providea home application on the home screen. A method of providing a homeapplication on the home screen has been described with reference toFIGS. 4 to 8, and thus further detailed description thereof will beomitted.

Referring to FIG. 18, when the home application 16 c on the home screenis touched for more than a predetermined time, the controller 180 mayenter into a display characteristic changing mode for the correspondingitem (S1401). The controller 180 may change a displayed size of the homeapplication 16 c based on a received drag input. When the displayed sizeis reduced to less than a predetermined size, the controller 180 maytransform (or change) the home application 16 c to the widget 16 b anddisplay the widget 16 b (S1402). Even after the displayed shape ischanged from the home application 16 c to the widget 16 b, thecontroller 180 may change the displayed size of the widget 16 b based ona received drag input. When the displayed size of the widget 16 b isreduced to less than a predetermined size, the controller 180 maytransform (or change) the widget 16 b to the shortcut icon 16 a anddisplay the shortcut icon 16 a (S1403).

Referring to FIGS. 17 and 18, the controller 180 having entered into thedisplay characteristic changing mode may also display an indicator 16 dindicating a direction along which the displayed size of the item 16 amay change. Accordingly, a user may intuitively identify in whatdirection the displayed size may change when the display characteristicsof the selected item are changed.

Referring to FIG. 19, when the shortcut icon 16 a displayed on thescreen is multi-touched, the controller 180 may enter into a displaycharacteristic changing mode for the shortcut icon 16 a (S1501). Uponreceiving a drag input starting at any one of the multi-touched pointswhile the shortcut icon 16 a is multi-touched, the controller 180 maychange a displayed size or a displayed shape of the shortcut icon 16 abased on the received drag input. For example, when the drag input isongoing to an area outside of an area where the shortcut icon 16 a isdisplayed, the controller 180 may expand the displayed size of theshortcut icon 16 a based on the drag path. When the displayed size ofthe shortcut icon 16 a is expanded to more than a predetermined size,the controller 180 may transform (or change) the shortcut icon 16 a tothe widget 16 b and display the widget 16 b (S1502). When a drag inputis continuously received in the direction of expanding the displayedsize even after the shortcut icon 16 a is transformed to the widget 16b, the controller 180 may expand the displayed size of the widget 16 band display the expanded widget 16 b (S1503). When the displayed size ofthe widget 16 b expands, predetermined information may also be added tothe widget 16 b. When the displayed size of the widget 16 b expands tomore than a predetermined size, the controller 180 may transform thewidget 16 b to the home application 16 c and display the homeapplication 16 c (S1504).

FIGS. 20 to 24 show examples of changing information displayed on anitem.

As a displayed size or shape of an item is changed, informationdisplayed on the item is also added or deleted. The type of informationdisplayed on the item may vary depending on the displayed size or shapeof the item.

For example, when an item is changed in a displayed shape to a widget,an execution result of an application corresponding to the widget may bedisplayed on the widget in the form of a preview. The informationdisplayed on the widget in the preview form may be added or deletedbased on the displayed size of the widget. For example, when thedisplayed shape of the item is changed to the widget, the controller 180may display on the widget an application corresponding to the widget ora list of functions of the corresponding application. As anotherexample, when the displayed shape of the item is changed to the widget,the controller 180 may display on the widget a list of content providedby the corresponding application. As an even further example, when thedisplayed shape of the item is changed to a home application, thecontroller 180 may display an execution image of the correspondingapplication on the entire screen. When the displayed size of a groupicon expands, the controller 180 may display a list of groupedcorresponding icons in the form of a widget.

Referring to FIG. 20, the controller 180 may display a shortcut icon 19a representing an email application on the home screen (S1601). When arequest for changing the display characteristics of the shortcut icon 19a is received and thus the displayed size of the icon 19 a expands, thecontroller 180 may transform the shortcut icon 19 a to a widget 19 b anddisplay the widget 19 b (S1602). Accordingly, the controller 180 maydisplay, on the widget 19 b, preview information related to the emailapplication, for example, a preview image of an email recently received.Thereafter, the information displayed on the widget 19 b may be newlyadded or changed depending on the displayed size of the widget 19 b. Asshown in FIG. 20, the information displayed on the widget 19 b may be apreview image of an execution result of the corresponding application.For example, in an example of an alarm application, preset alarminformation may be displayed on the widget. In the example of ascheduling application, preset scheduling information may be displayedon the widget, and the scheduling information may be changed from dailyscheduling information through weekly and monthly scheduling informationto yearly scheduling information depending on the displayed size of thewidget.

Referring to FIG. 21, the controller 180 may display a shortcut icon 20a representing an address book application on the home screen (S1701).When the displayed size of the shortcut icon 20 a expands, thecontroller 180 may display a list of applications or functionsexecutable in association with the address book application incombination with the shortcut icon 20 a in the form of a widget 20 b(S1702).

Referring to FIG. 22, the controller 180 may display a shortcut icon 21a representing a memo application on the home screen (S1801). When thedisplayed size of the shortcut icon 21 a expands, the controller 180 maydisplay a widget 21 d combined with a list 21 b of pre-stored memosdisplayed in the form of a preview image and a list 21 c of applicationsexecutable in association with the memo application rather than theshortcut icon 21 a (S1802).

Referring to FIG. 23, the controller 180 may display a shortcut icon 22a representing an album application on the home screen (S1901). When thedisplayed size of the shortcut icon 22 a expands, the controller 180 maydisplay any one of a plurality of pre-stored images in the form of awidget 22 b (S1902). When the displayed size of the widget 22 b expandsto more than a predetermined size, the controller 180 may display a list22 c of pre-stored widgets on the widget 22 b (S1903). A number ofimages displayed in the preview form on the widget 22 b from amongimages included in the image list 22 c may vary depending on thedisplayed size of the widget 22 b. Accordingly, the image list 22 c maybe divided into a plurality of pages. The controller 180 may display anyone of the plurality of pages on the widget 22 b. The controller 180 mayshift (or change) the page to another page and display the shifted page(or changed page) based on a received drag input in an area where thewidget 22 b is displayed (S1904).

Referring to FIG. 24, the controller 180 may display a group icon 23 acorresponding to a group of items on the home screen (S2001). When thedisplayed size of the group icon 23 a expands, the controller 180 maydisplay a list 23 c of the grouped items in the form of a widget 23 b(S2002). The list of the grouped items may be divided into a pluralityof pages depending on the displayed size of the widget 23 b. Thecontroller 180 may display any one of the plurality of pages on thewidget 23 b. The controller 180 may shift or change the page includingthe list 23 c to another page and display the shifted page (or changedpage) based on a received drag input in an area where the widget 23 b isdisplayed (S2003).

Referring to FIG. 14, while changing the display characteristics of theitem, the controller 180 may receive a request for terminating thedisplay characteristic changing mode. For example, while changing thedisplay characteristics of the item based on a received drag input, thecontroller 180 may receive a request for terminating the displaycharacteristic changing mode when a touch input is received at adifferent area from an area where the item is displayed. While changingthe display characteristics of the item based on a received drag inputwhile the item is multi-touched, the controller 180 may receive arequest for terminating the display characteristic changing mode when atouch input of at least one of a plurality of multi-touched points isreleased.

In response to the request for terminating the display characteristicchanging mode for the item (S1105), the controller 180 may terminate thedisplay characteristic changing mode for the selected item (S1106). Uponterminating the display characteristic changing mode, the controller 180may map the changed display characteristics with the corresponding itemand store the mapped result in the memory 160. The controller 180 maydisplay a message asking whether to store the changed displaycharacteristics on the screen. Upon receiving a control input forstoring the changed display characteristics from a user, the controller180 may also map the changed display characteristics with thecorresponding item and store the mapped result in the memory 160. Instoring the changed display characteristics in the memory 160, whenreentering into the page of the home screen currently displayed, thecontroller 180 may display the item reflecting the changed displaycharacteristics based on the display characteristics stored in thememory 160.

Upon changing the displayed size of an item on the home screen, anarrangement space in the home screen may be insufficient. The mobileterminal 100 may solve problems of insufficient arrangement space invarious methods.

When entering into a display characteristic changing mode for the item,the controller 180 may display a direction indicator indicating adirection in which the displayed size of the item is changeable on thescreen. Referring to FIG. 25, the controller 180 displays a directionindicator 24 b indicating a direction in which the displayed size of anitem 24 a may change. For example, when there is an extra arrangementspace under the item 24 a, the controller 180 may display the directionindicator 24 b indicating that the displayed size of the item 24 a mayexpand in a lower direction.

When it is difficult to further expand or shrink the displayed size ofthe item, the controller 180 may display information indicating such afact on the screen. Referring to FIG. 26, the controller 180 may enterinto a display characteristic changing mode for an item 25 a (S2101).Accordingly, the controller 180 may change the displayed size of theitem 25 a based on a received drag input. When receiving a drag inputallowing the displayed size of the item to expand to an area on whichanother item 25 b is displayed or to an area other than an area on whichthe item may be displayed while the displayed size changes, thecontroller 180 may display a message 25 c indicating that the displayedsize of the item 25 a may not expand (S2102).

When there is an attempt to expand the displayed size of the item beyondan expandable area, the controller 180 may add a new page in the homescreen. In addition to adding the new page, the controller 180 may alsorearrange the item whose displayed size has been expanded and the otheritems arranged on the same page as the corresponding item on the newlyadded page. Referring to FIG. 27, the controller 180 may enter into amode of changing the displayed size of an item 26 a on the home screen(S2201). Accordingly, the controller 180 changes the displayed size ofthe item 26 a based on a received drag input. When the arrangement spacefor items is insufficient in the page P1 on which the item 26 a isarranged as the displayed size of the item 26 a is expanded, thecontroller 180 may add a new page P2 in the home screen.
